Profile: It was a nice comeback season for Isringhausen, who pitched a significant number of innings for the first time since 2008. While his 8.49 strikeout rate was acceptable, his 4.63 walk rate limits his ceiling. Isringhausen carries the valued role of "proven closer" as evidenced by his 300 career saves. If he catches on with a team, he might have a chance to pick up save opportunities just based on his past success in the role. That's basically what happened last year. (Chris Cwik)

The Quick Opinion: He had a nice comeback season, but the only reason he'll receive a prominent bullpen role is his reputation. The "proven closer" tag makes Isringhausen a sneaky candidate to pick up saves in the right situation, but things would have to go to hell for a team to move him to the role.
